I called them and was told that early 68 used a different core that is not available. My upper tube is slightly crushed from changing out the old hard hose years ago. After looking at core dimensions for a 67, I think it might fit. Anyone know if a 67 is the right one? My firewall doesn’t have the oval hole for the angled lower tube.

Let me go out to my 68 today in the garage to examine heater core at firewall of my VERY early car. In fact, that car was produced on August 9, 1967 - the first 68 GTO convertible ever made (built 1st hour of production at Pontiac). What I can't validate is if this heater core was ever replaced.
If I recall from last look, the top tube was straight, but the lower tube might bend upward. Also, I have an original 68 heater core (good) on my bench I can look at. More after work day concludes.
UPDATE: Call ended early so I dashed out to look. Lower tube bends on the installed core in my convertible. Replaced? Perhaps. Still together so I don't know. Pictures of '67 cores show straight tubes, but I don't have one to measure.
